Abstract

1. Способ приема информации управления из множества форматов информации управления на каналах управления в системе мобильной связи, в котором каждый из каналов управления сконфигурирован согласно одному из множества форматов информации управления, отличающихся числом битов, причем способ содержит этапы, на которых:принимают число элементов физического ресурса, содержащих модулированную информацию управления по меньшей мере одного из каналов управления,демодулируют модулированную информацию управления по меньшей мере одного канала управления с использованием данной схемы модуляции для получения битов кодированной информации управления каналов управления, идекодируют биты кодированной информации управления по меньшей мере одного канала управления,получают число битов кодированной информации управления, которое является целым кратным наименьшему допустимому числу битов кодированной информации управления для всех форматов информации управления.2. Способ по п.1, в котором модулированную информацию управления передают на элементах ресурса физических каналов управления нисходящей линии связи, и способ дополнительно содержит этап, на котором осуществляют слепое обнаружение только на подмножестве элементов физического ресурса, на которые может отображаться модулированная информация управления, и/или только на подмножестве форматов информации управления.3. Способ по п.1 или 2, причем способ осуществляется объектом принимающей стороны, осуществляющим связь с базовой станцией.4. Способ по п.3, в котором объект принимающей стороны представляет собой мобильную станцию.
